the central station.

The inventionis an `improvement on the device described and illustrated 1n British `Patent No. 14.431 of 1908, and one of the olijectsV of the invention is to .provide an improved construction of interrupter at the central or transmitting station.

The invention will-'be more fully understood by reference to the accompanying drawings, wherein,

Figure l of the accompanying' drawing is a diagram of the installation of the trans- -nutting s `rtion and oi' a receiving station.

Figs. 2 and Q are together a sectional elevation of the transmitting and tell-tale apparatus, the installation being assumed b v way of example to be applied to the control of four receiving stations; the section being interrupted and showing only two of the interruptor devices and one of the operating motors 37, 38 of the corresponding tell-tale hand 4. Figs. 3 and 3a are together a-plan corresponding to Fia. 2 with partial section along the axis of one of the interrupters. Fig. tis a detail sectional elevation on the line A A in Fig. 2 showing the parts ot the interrupter and the engaging pawls 75, 7G

Figs. 7, 8 and 9 show respe'ctiv'eliy in sectional elevation and in plan a` third position. Figs. 10. and 11 show the parts in a fourth position in elevation and in sectionalplan. Fig. 12 is a front. elevation of the device installed at the receiving tion and mounted uponr the vshaftA '1l driven by the motor z' i of this station' Fig. 13 isA a corresponding` lony gitudinalelevation; 14 is a plan.

This separation presents the tolhifwing advantages; the rod 24 is guided at its two ends and is not inla 1' movement directly by hand. The operaior has only to exert asmali c ti'ort upon the. hand wheel in order to displace the rod and all the interrupters carried thereby.

As f sent into the motors and a'n given -a large anseeing tlat the interrupter has remained in the sainer position relatively to the Contact pieces o and .p because the supplementary rotation of the hand wheel in th reverse direction has lef-t the interruptor; engaged in the desired position.

Another improvement forming the object of the present application4 consists, in practical constructional form of the device for the transmission of current impulses between the motors z' fr of the receiving stations and the electromechanical esca ements of the transmitting station. T is novel arrangement is represented in detail in Figs. l2, 123 and let audindicated dla-.

grammatically in Fig. 1. Two contact' pieces a and w are secured to the upright d of the supporting frame 44 of the shaft d; these contact pieces are connected by conductors and 3/--4/ respectively to the electromagnet, the core of which serves to attract the finger 3l of the electromechanical 9 escapement of the motor 37-38 and with the source of current. Opposite these tixed vContact pieces two Contact pieces u are adapted to more; they are united by a conducting bridge u which is carried by a rod 77. The lat-ter is guided between rollers 78 jour aled on the frame zi; at its upper end it forms a pivot tor one of the branches of two bent levers79-80 which are themselves piyoed tothe frame ci at l. The branches 80 of these levers embrace one of the ends oi a rod @passing through a slot in the frame d and carried by a rocking lever 83 pivoted. to the said frame; the other end of the rod SQ forms a roller and constantly bears upon a disl s furnished with a series of notches or recesses along an arc of a circle (Fig. l2). When the shaft l ro-A tates it carries in its movementlthe recessed disk s; this disk imparts to the lever 83 a rocking movement which transmitted to the bent levers S0-7J and produces an alternating movement ci the rod 77, In this movement the Contact pieces u are alternately broughtI into contact with the contactpieces :a and fu and separated from them. Each time contact Ais established a current impulse is sont into the electromagnct of the elcctro-n'iechanicalI escapement of the motor 2 38. rlhis arrangement which is essentially mechanical presents advantages in the sense that it permits of dispensinoA with sliding contactsn the operation of which is uncertain vand also permits of indefinitely increasing the number of cur-' escapementassociated' with 'said vindicator `rent impulses" transmitted to t-lie motors actuatingr Vtl'ie tell-tale hands.

sfwill be readily understood the arrangement of the rocking lever, actuated` i 5bby he notched diskfor thief production of the. alternating movement of the contact ieees .it enables the direct-ion of rot-ation .of the shaft d to be'reversed atv any moment.
